I thought it would be a waste of time (both human and mechanical).
The existing usage of upper/lower in the regression tests is plenty
to detect basic problems. As for advanced problems, the only
interesting aspect of upper/lower is locale-dependent behavior, which
the main regression tests are singularly unsuited to test for.
It might be interesting to expand src/test/locale/, but that stuff
needs far more work than just addition of upper/lower tests ...
